dolyame-ui-inlineeditnpm
dolyame-ui-inlineedit is a confirmed malicious npm package (MAL-2026-13573) that typosquats a legitimate package to trick installs (malicious version 35.8.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-ui-inlineedit (npm)
What this malware does
The package presents itself as a data-transformation/UI utility but on require() unconditionally loads setup.js and lib/telemetry.js, both of which implement an install/import-time dropper. Hostnames are assembled at runtime via array.join() to evade static analysis, resolving to Cloudflare Workers subdomains under oob-worker.cf10{0-3}-*.workers.dev with a DNS TXT fallback across sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. A platform-specific binary is downloaded, written to a hidden path under /var/tmp (or a disguised.exe on Windows), permissions are set to 0755 via bracket-access fs["chmod"+"Sync"], and the binary is spawned detached through /bin/sh -c or cmd.exe with.unref(). The fetched bytes are opaque with no signature or hash verification. lib/telemetry.js replicates the same primitives inside base64-decoded chunks and is the package's module.exports, so ordinary require() of the package triggers execution. Cover-story comments referencing SHA-256 integrity checks and DISABLE_TELEMETRY/DO_NOT_TRACK opt-outs are inserted alongside the dropper to mimic legitimate telemetry.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dolyame-ui-inlineedit (version 35.8.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging dolyame-ui-inlineedit across your stack and pipelines.
If you installed it — respond
dolyame-ui-inlineedit is a typosquat — you almost certainly intended a legitimately-named package. Remove dolyame-ui-inlineedit, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If dolyame-ui-inlineedit was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks dolyame-ui-inlineedit before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
